Variable amount recurring billing

- by Dave Newman

Hi i'm looking for a payment gateway that can do recurring billing that changes month to month. Fogbugz do this, they charge based on how many active users there were that month. All of the APIs that i've found only let you set a fixed amount and it's difficult/impossible to vary the subscription amount month to month. Has anyone come across any services that do this?

What does this WCF error mean: "Custom tool warning: Cannot import wsdl:portType"

- by stiank81

I created a WCF service library project in my solution, and have service references to this. I use the services from a class library, so I have references from my WPF application project in addition to the class library. Services are set up straight forward - only changed to get async service functions. Everything was working fine - until I wanted to update my service references. It failed, so I eventually rolled back and retried, but it failed even then! So - updating the service references fails without doing any changes to it. Why?! The error I get is this one: Custom tool error: Failed to generate code for the service reference 'MyServiceReference'. Please check other error and warning messages for details. The warning gives more information: Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: List of referenced types contains more than one type with data contract name 'Patient' in namespace 'http://schemas.datacontract.org/2004/07/MyApp.Model'. Need to exclude all but one of the following types. Only matching types can be valid references: "MyApp.Dashboard.MyServiceReference.Patient, Medski.Dashboard, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" (matching) "MyApp.Model.Patient, MyApp.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" (matching) XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:portType[@name='ISomeService'] There are two similar warnings too saying: Custom tool warning: Cannot import wsdl:binding Detail: There was an error importing a wsdl:portType that the wsdl:binding is dependent on. XPath to wsdl:portType: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:portType[@name='ISomeService'] XPath to Error Source: //wsdl:definitions[@targetNamespace='http://tempuri.org/']/wsdl:binding[@name='WSHttpBinding_ISomeService'] And the same for: Custom tool warning: Cannot import wsdl:port .. I find this all confusing.. I don't have a Patient class on the client side Dashboard except the one I got through the service reference. So what does it mean? And why does it suddenly show? Remember: I didn't even change anything! Now, the solution to this was found here, but without an explanation to what this means. So; in the "Configure service reference" for the service I uncheck the "Reuse types in the referenced assemblies" checkbox. Rebuilding now it all works fine without problems. But what did I really change? Will this make an impact on my application? And when should one uncheck this? I do want to reuse the types I've set up DataContract on, but no more. Will I still get access to those without this checked?

ASP.NET MVC hosting problem, routing, handlers and modules

- by johnabs

Hi, This is one of them again, hosting with fasthosts. I recently purchased a windows developer package from them. When I tried to deploy my ASP.NET 3.5 MVC project, which was working fine with the same host on a reseller account, it is not working. The reason to move from reseller to a normal Windows Developer package is, the MS-SQL server database is too expensive in a reseller account, strange! I contact them, and they are saying they upgraded the control panel. The technical support said, I need to disable the Modules and Handlers from the web.config file. Also I need to deploy them as .dll files. I am not sure how to do that. The website is partially working now. I think the problem is now with the routing. I have not deployed any .dlls apart from the System.Web.Mvc.dll, System.Web.Routing.dll and System.Web.Abstractions.dll. I have not got a clue on how to deploy the Modules and Handlers. The code that I commented on the web.config file is as follows.  Anybody got any ideas please. Thank you for your time.

Parsing a file with hierarchical structure in Python

- by Kevin Stargel

I'm trying to parse the output from a tool into a data structure but I'm having some difficulty getting things right. The file looks like this: Fruits Apple Auxiliary Core Extras Banana Something Coconut Vegetables Eggplant Rutabaga You can see that top-level items are indented by one space, and items beneath that are indented by two spaces for each level. The items are also in alphabetical order. How do I turn the file into a Python list that's something like ["Fruits", "Fruits/Apple", "Fruits/Banana", ..., "Vegetables", "Vegetables/Eggplant", "Vegetables/Rutabaga"]?

How do I use an ADO.NET managed provider in Excel?

- by Eli

I have an ADO.NET Managed Data Provider that is registered in machine.config in DbProviderFactory - It is available for use from, say, Analysis Services, so I know it is correctly registered. However, I need to be able to query the managed provider from Excel, but the managed provider doesn't appear as a choice from Data Link Properties | All Ole Db Providers. How do I get an ADO.NET Managed Data Provider to appear there, or is there another technique I need to use? Thanks in advance, Eli.

Using oAuth (Twitter, LinkedIn) for login to a web app

- by novaurora

Should I use oAuth, for example LinkedIn or Twitter, as my signin mechanism for my app? It seems that most apps just use oAuth to connect other services to it, but they make you set up your own user/password after you use oAuth (including StackOverflow), and I'm not really sure why this is. Would love some insight here. Thank you.

SoapUI JMS Connections

- by Damo

I am using SoapUI to do performance testing of some services over JMS using WebSphere MQ as the JMS Provider. SoapUI uses HermesJMS to provide the JMS Connection details for the JMS Endpoint. I've noticed that when I call a request from SoapUI the JMS Connection is never closed. This results in hundreds of SYSTEM.DEF.SVRCONN channel connections. It seems to be specific to SoapUI as HermeJMS doesn't exhibit this behaviour. Has anyone else seen this?

Index out of bounds error

- by sprasad12

Hello, I am working on a program where i am recreating the saved widgets back on to the boundary panel. When i am creating them i am also trying to put the values into the ArrayList so that if i want to update and save the opened project i should be able to do so by getting the values from the ArrayList. Here is how the code looks like: for(int i = 0; i < result.length; i++){ if(ename.contains(result[i].getParticipateEntityName())){ ername.add(ename.indexOf(result[i].getParticipateEntityName()), result[i].getParticipateRelatioshipName()); etotalpartial.add(ename.indexOf(result[i].getParticipateEntityName()), result[i].getTotalPartial()); }else if(wename.contains(result[i].getParticipateEntityName())){ wrname.add(wename.indexOf(result[i].getParticipateEntityName()), result[i].getParticipateRelatioshipName()); } } Here ename, ername, etotalpartial, wename and wrname are all ArrayList. This piece of code is included in an asynchronous class method. When i run the code i get error at "ername.add(ename......". Here is the error stack: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0 at java.util.ArrayList.add(ArrayList.java:367) at com.e.r.d.client.ERD1$16.onSuccess(ERD1.java:898) at com.e.r.d.client.ERD1$16.onSuccess(ERD1.java:1) at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:216) at com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java:287) at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:393) at sun.reflect.GeneratedMethodAccessor16.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessagesWhileWaitingForReturn(BrowserChannel.java:1713) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:165) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:188) at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessages(BrowserChannel.java:1668) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:401) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Thread.java:619) I am not sure what i am doing wrong.

How to maximize http.sys file upload performance

- by anelson

I'm building a tool that transfers very large streaming data sets (possibly on the order of terabytes in a single stream; routinely in the tens of gigabytes) from one server to another. The client portion of the tool will read blocks from the source disk, and send them over the network. The server side will read these blocks off the network and write them to a file on the server disk. Right now I'm trying to decide which transport to use. Options are raw TCP, and HTTP. I really, REALLY want to be able to use HTTP. The HttpListener (or WCF if I want to go that route) make it easy to plug in to the HTTP Server API (http.sys), and I can get things like authentication and SSL for free. The problem right now is performance. I wrote a simple test harness that sends 128K blocks of NULL bytes using the BeginWrite/EndWrite async I/O idiom, with async BeginRead/EndRead on the server side. I've modified this test harness so I can do this with either HTTP PUT operations via HttpWebRequest/HttpListener, or plain old socket writes using TcpClient/TcpListener. To rule out issues with network cards or network pathways, both the client and server are on one machine and communicate over localhost. On my 12-core Windows 2008 R2 test server, the TCP version of this test harness can push bytes at 450MB/s, with minimal CPU usage. On the same box, the HTTP version of the test harness runs between 130MB/s and 200MB/s depending upon how I tweak it. In both cases CPU usage is low, and the vast majority of what CPU usage there is is kernel time, so I'm pretty sure my usage of C# and the .NET runtime is not the bottleneck. The box has two 6-core Xeon X5650 processors, 24GB of single-ranked DDR3 RAM, and is used exclusively by me for my own performance testing. I already know about HTTP client tweaks like ServicePointManager.MaxServicePointIdleTime, ServicePointManager.DefaultConnectionLimit, ServicePointManager.Expect100Continue, and HttpWebRequest.AllowWriteStreamBuffering. Does anyone have any ideas for how I can get HTTP.sys performance beyond 200MB/s? Has anyone seen it perform this well on any environment?

THe goal is if a depdendency cannot be found in the outter container then i would like to then search the inner container. How can i achieve this ?
